I downloaded this flutter app template from here - https://flutterawesome.com/ui-implementation-of-coffee-shop-app-for-flutter/
But when I tried to run the app on Android, but it is returning this Error
Launching lib\main.dart on Android SDK built for x86 in debug mode...
'UI' is not recognized as an internal or external command,
operable program or batch file.
Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain
Caused by: java.lang.ClassNotFoundException: org.gradle.wrapper.GradleWrapperMain
Running Gradle task 'assembleDebug'... 314ms
Exception: Gradle task assembleDebug failed with exit code 1
I'm developing this app, for both iOS and Android. How do I fix this issue?
